Price difference
The price of silver carp is higher, which is about11~1kg in 5 yuan in southern China, but the price of silver carp is lower, which is 8 yuan 6 ~ 1 kg. The bigger the fish, the higher the price of fish, and the volume of silver carp is higher than that of silver carp.
Appearance observation difference
Silver carp skin spots are a little dark, and silver carp skin spots are a little purple. If the water environment is better, silver carp will have some fluorescence under the sunlight, from the appearance observation.
Judging from the posture of the two kinds of fish, it is mainly manifested in the lower part of the ventral fin of the two kinds of fish. There is a very obvious convex line in the abdomen of silver carp, which continues to the end of the body, while this convex line in Hualien is not very obvious, which is also a very obvious difference.
The head of silver carp is relatively large, accounting for 1/3 of the body, so it is also called bighead carp. The fish head with chopped pepper made by silver carp is not only delicious, but also more expensive, which is also a big difference.
Differences in food
The two kinds of fish have different carnivorous habits. Silver carp eat duckweed for a living, such as duckweed in the pond and some black algae in the pond, all of which are the results of silver carp. Of course, silver carp is not necessarily a vegetarian, but also eats a little plankton, and silver carp mainly eats plankton food.
These two kinds of fish have made great achievements in eliminating black algae. In a lake, if cyanobacteria break out, a corresponding number of silver carp should be put in at the same time, so that the actual effect of removing black algae will be better.
From the price of fish, it is definitely more profitable to cultivate silver carp, because the price of silver carp is higher than that of silver carp, and the price of silver carp is higher because its fish head can make delicious chopped pepper fish head, which has corresponding nutrients and is very popular with people, so it is more profitable to cultivate silver carp.
